Zuhl

The one-horned, aged, hunchback, toothless scientist, one of Prince Heinel's original aides. His invention of the Anti-Super Electromagnetic Device nearly destroyed Voltes V.

Cunning and contemptuous, he discreetly captured Prof Go just before he returned to Earth and attempt to use him for his plans to kill Heinel and Voltes V.
Eventually, his attempt to betray Heinel failed and he was executed.
